INTERACTIVE PERIODIC TABLE
• Explore all 118 elements with 4 levels of detail
• View atomic structure, electron configuration, physical properties, discovery history, and real-world uses
• Pinch to zoom, tap for details, and use landscape wide-view mode
• Filter by element group, metal type, and state of matter

EQUATION BALANCER
• Balance chemical equations automatically with matrix-based math
• Supports hydrates, nested formulas, and state symbols: (s), (l), (g), (aq)
• Fast, accurate results for simple and complex equations
• Great for homework, revision, and classroom use

MOLAR MASS CALCULATOR
• Calculate molar mass for chemical formulas in seconds
• See a full breakdown by element: count, atomic mass, subtotal, and percentage
• Supports formulas like H2O, Ca(OH)2, Al2(SO4)3, and CuSO4·5H2O
• Clear formula display makes results easy to read

ION REFERENCE
• Study 40+ ions with detailed information pages
